Coupling between two monopole antennas on a slotted finite ground plane

In this paper, coupling between two monopole antennas on a slotted finite ground plane is considered. The hybrid method of moments (MEM) and the geometrical theory of diffraction (GTD) are applied to solve the problem. A coupling coefficient is introduced to evaluate the coupling between two antennas. Measured and calculated coupling coefficients and radiation patterns are in good agreement.
